To all whom ii, may concern:

Be it known that I, JAcoB KAUFMANN, acitizen of the United States, residing at Philadelphia, in the county of Philadelphia it has particular relation to improved means j for supporting the heddle bars intermediate their ends.

The principal object of my invention is to provide improved means for supporting the heddle bars intermediate their ends which "will be simple, durable, and eflicient and which will permit the heddle bars to be readily assembled and detached from the frame. My invention contemplates a device for the aforesaid purpose which will more effectively prevent sidewise displacement and.

distortion of the heddle bars in the frame which has heretofore been the cause of much damage.

My invention further contemplates a form of device which, while effectively reducing wear upon the heddle bars at the place of support, will not of itself be the means of foulin .with adjacent frames in the loom whent e same are rapidly reciprocated with respect to each other.

'lhenature and characteristic features of my inventionwill be more readily understood from the following description taken in connection with the. accompanying drawings forming part hereof, in whih- Figure 1' 's an elevational view of a heddle frame provided with means embodying the main features of my present invention; Fig. -2 isan enlarged fragmentary detail view,

partly in elevation and partly in section, of a portion of the structure shown in Fig." 1 illustrating the parts constituting the novel elements of my invention; Fig. 3 is a transverse vertical=-section taken on the line 33 of Fig. 2; and Fig. 4 is a perspective view illustrating the supporting link detached.

Referring to the drawings, the" heddle frame there shown is of a common and well known type comprisin the top and bottom bars 5 usually made 0 wood and connected at their ends by metallic straps or bars 6.

Application filed August 10', 1915. Serial No. 44,688.

the heddles 8 are mounted in the usual or any desired manner.

At the places where it is desiredto support the heddle bars intermediate their ends, the inner portions of the top and bottom bars 5 are recessed as at 9, the recesses being less deeply out near their ends to provide seats 10 upon which rest the cars 11 provided at the ends of auxiliary supporting bars 12. The auxiliary supporting bars 12 are disposed within the recesses 9 and extend within said recesses in the same general direction as'th'e top and bottom bars 5 a distance suflicient for the required amount of sidewise movement of the heddle bar sup porting links hereinafter referred to. The preferred manner of forming the. bars 12 is to take a strip of metal of substantially rectangular cross section and twist the end portions thereof to form the ears 11 above referred to. The cars 11 of the bars 12 are apertured for the fastening screws 13 which pass therethrough and are secured in the ars 5.

The heddle bar supporting links 14, shown in perspective in' Fig. 4 of the drawings, are slidably but non-rotatably mounted upon the auxiliary supporting bars 12 and'comprise open-sided links formed of a strip of metal of rectangular cross section of sufficient width to provide an effective bearing surface both upon the auxiliary supporting bar 12 and the heddle bar 7 the ends of this strip being bent over-at one end as at 15 and atthe other end as at 16 to form the link as clearly shown in said Fig. 4 of the drawings. The longer axis in cross-section of the strip from which said link is formed is disposed. parallel to the longitudinal extension of theframe. I V I It will be. noted that the recess 9 in the top or bottom bar 5 is of sufficient depth to allow the link 14 to freely move upon the 'auxiliarysupporting bar 12 in'a longitudinal direction but that the turned over end 15 snugly engages the bar 12 so as to prevent torsional or swinging movementof the link 14' -With respect to the frame and that the turned over end 16 likewise snugly engages the heddle bar 7 so as to prevent rotation It will also be or cut through the heddle bar 7 or the supporting bar 12' at any particular point as occurs when links or rigid hooks of relatively smaller width are employed as has heretofore been the uniform practice; and furthermore, it will be noted that the link 14 while much stronger than the supporting links heretofore used at the same time is of less thickness so as in itself t, form no obstruction projecting beyond the faces of the heddle frame proper which would tend to foul on the parts of adjoining heddle frames as the same are reciprocated with respect to each other in the loom. F urthermore, by mounting the supporting bars 12 in the recesses 9 there will be no interference by these bars with the ends of the heddles which are mounted upon the bars 7 as has.

heretofore been the case where slidable supporting hooksh'ave been used.

Having thus described the nature and characteristic features of my invention what I claim as new and desire to secure by Letters Patent is:

1. In a heddle frame, means for support mg the heddle bars intermediate their ends.

comprising auxiliary supporting bars mounted in recesses in the top and bottom bars of the heddle frame, and links slidably and non-rotatably mounted on said aux-' iliary supporting bars, the heddle bars bemg non-rotatably mounted in said links, and said links being formed of a strip of fiat metal having its longest axis in crosssection disposed parallel to the longitudinal extension of the frame. Y

2. In a heddle frame, means for supporting the heddle bars intermediate their ends mounted in recesses in the top and bottom bars of the heddle frame, and open sided links slidably and non-rotatably mounted on said auxiliary supporting bars, the neddle bars being non-rotatably mounted in said links, and said links being formed of a strip of flat metal having its longest axis in crosssection disposed parallel to the longitudinal extension of the frame.

3. In a heddle frame, means for supporting the heddle bars intermediate their ends comprising auxiliary supporting bars mounted in the top and bottom bars of the heddle frame and open sided links slidably and non-r0 atably mounted on said aux- I iliary supporting bars, the heddle bars being non-rotatably mounted in said links, said links being formed of a strip of fiat metal having itsends bent over. 3 h 4:- ln a heddle frame, means for support-' ing theheddle barsintermediate their ends comprising auxiliary supporting bars mounted in the top and bottom bars of the heddle frame, and open sided links slidably' and. non-rotatably mounted on said aux-' iliary supporting bars, the heddle bars being non-rotatably mounted in said links, said links being formed of a strip of fiat metal having its ends bent over and having its longest axis in cross-section disposed parallel to the longitudinal extension of the frame.

In testimony whereof, I have hereunto signed my name.
